These are alternate interior angles.
you would set them equal to eachother and solve for x.
10x=9x+7
subtract 9x from 10x.
x=7
the answers are bolded.
I hope this helps
3(x - 1) = 2x + 9
3x - 3 = 2x + 9
3x (-2x) -3 (+3) = 2x (-2x) + 9 (+9)
(3x -2x) = (9 + 9)
(x) = (18)
x = 18
x = 18 is your answer
hope this helps
